Plenty of crowing sound files to be found via googling.
Did the walk later this morning as my wife went with us. Walking past the same field a pair of Honkers were feeding, Bella was just watching them. Somewhere in the distance a rooster crowed, and she wound up got excited and started scanning for movement etc.
She is going to be 6 this year and I was hoping to make a trip to SD but I fear the long cold winter put a hurting to the birds? Otherwise I might delay deer hunting a week to hit the opener. I have a spot that has lots of bird, only issue my access requires significant walk.
